  Wavelength Division Multiplexer (WDM) is a technology that simultaneously transmits multi-wavelength optical signals on a single optical fiber. The wavelengths of the digital signals carried by these optical signals can be at the same rate and in the same data format, or at different rates and in different data formats. By adding new wavelength characteristics, the network capacity is determined according to user requirements. For WDM below 25Gb/s, current technology can completely overcome the limitations imposed by fiber dispersion and fiber nonlinear effects to meet various requirements for transmission capacity and transmission distance. WDM realizes two-way communication and low-cost upgrade of optical network capacity. The wavelength division multiplexer can be divided into a wavelength divider at the transmitter and a wavelength division multiplexer at the receiving end. The optical multiplexer is used at the transmission end of the transmission system and is a device with...
